1. Painting over old wall paint
No longer like the colour of your walls and want to give your home a new look? To do this, you don’t necessarily have to remove the existing wall paint. In many cases, you can simply paint over it. This saves time and money.
For this, use an opaque colour. This means that the paint should have a high pigment density. This ensures that the old colour does not show through.
Important: for you to be able to paint over old paint, it must be clean, dry and sound. For example, it must not be flaking. Mould stains should be removed rather than painted over.
Don’t want to put in too much effort and still get a perfect result? Then it may be worth leaving the painting work to a professional.
2. How can you remove dried paint?
There are already many layers of old paint on the wall? If so, it’s worth removing the old wall paint before repainting. Old emulsion paint cannot be repainted indefinitely.
There are different ways to remove old paint from the walls. These include:
On a smooth wall surface, you can usually remove paint with a scraper. However, you’ll need a lot of perseverance and patience for this. It’s best to use a sharp, sturdy scraper.
You can remove wall paint using sandpaper or a sanding machine. This method is only suitable for smooth wall surfaces.
Sanding paint off requires a lot of manual skill in addition to the right machine. Working with a sanding machine is noisy, dangerous and dusty. It’s best to leave this work to a professional.
Attention: Care should be taken when sanding down old wall paints. This is because in buildings constructed before 1990 there may be asbestos in the materials contained. Inhaling asbestos can be extremely harmful to your health.
When the walls are sanded down, asbestos fibres can be released. Therefore, you should have a professional asbestos analysis carried out before starting the work. If asbestos is detected, you should have the work carried out by an asbestos remediation company.
Do you want to remove all layers of paint from a wall? If so, you can knock off the wall paint. In doing so, this removes not only the paint, but also the plaster base.
Before you can repaint the wall, you need to replaster it. To obtain a smooth surface, however, you need a lot of experience. It’s best to leave this work to a professional.
Were your walls painted with water-based paints ? If so, you can usually remove the paint with water.
It is best to use lukewarm water, a sponge and a brush. This allows you to remove the wall paint bit by bit. This method requires a lot of patience and can be physically demanding.
Good to know: often, a superficial clean with soap and water is sufficient. This will allow you to remove coarse dirt and paint residue.
Has your wall been painted with acrylic, lacquer or latex paint. If so, you can heat the wall paint with a hot air gun. The heat separates the paint from the substrate. You can then remove it with a spatula.
Please note: When using this method, the surface must not be flammable, as the paint is heated to a high temperature. Heat-resistant surfaces are, for example, metal or stone.
If you have not achieved the desired results with the other methods, you can try chemical paint removers. These are also known as «paint strippers». Depending on the surface, use an alkaline or solvent-based paint stripper.
Apply the paint stripper to the wall with a brush and let it take effect. Then wipe the paint away with water.
This method should be the last choice as it is harmful to the environment and your health.
Note: First, test the stripper somewhere inconspicuous to see whether the substrate can withstand it.
Removing wall paint: Protect yourself properly
When removing wall paint, harmful by-products such as fine dust or toxic fumes may be produced. Therefore, always protect yourself with a respiratory mask, goggles and work gloves. In addition, ventilate the rooms regularly.
3. Removing wall paint: challenges
Removing wall paint can be a challenging task. This is especially true for stubborn paints, such as emulsion paints, or for sensitive surfaces such as wood. Find out here how to deal with these challenges.
How can I remove emulsion paint?
Emulsion paint forms a solid, durable layer on the wall. It adheres well to various surfaces. This makes removing emulsion paint tedious.
Emulsion paint is water-based. First, test somewhere inconspicuous to see whether you can dissolve the wall paint with water. If the paint cannot be removed in this way, you can try sanding it down. You may even need to remove the paint with solvent.
Important: when choosing a method, pay attention to the surface. This is because not every method is suitable for every surface, and in the worst case, it can even damage the surface.
How can I remove old paint from wood?
To remove old coats of paint from wood surfaces, the following methods are suitable: scraping or sanding down. If this does not achieve the desired result, you can also resort to paint strippers.
Do you only want to remove small splashes of paint from wood? Put some linseed oil on a cloth and place it on the affected area for about a minute. After that, you can try carefully removing the paint with a scraper.
What is the quickest way to remove paint from metal?
You can remove paint from metal using almost all methods available. This is because many types of metal are insensitive and heat-resistant. However, first test each method somewhere inconspicuous to see whether it might damage the metal.
4. Removing paint stains from clothes
Have you discovered a fresh paint stain on your clothes? Then it’s best to act immediately.
Remove as much paint as possible from the stained area. The best way to do this is with a scraper. Spoons or blunt knives, for example, are also suitable for use as scrapers.
Turn the garment inside out. This will prevent the paint from penetrating deeper into the fibres.
Soak the affected area with water and a mild detergent.
After a exposure time of a few minutes, you can wash out the paint stain with cold water.
Repeat this process if the paint has not been removed completely.
Did you only notice the paint stain once it had already dried?
Soak the affected area in water – the longer, the better.
Apply a mild cleaning product to the affected area. Leave the cleaning product on the affected area for a few minutes to take effect.
Gently rub the paint stain with a clean cloth.
For stubborn stains, you can also use home remedies such as baking powder, lemon juice or vinegar use. Apply the home remedy to the affected area and let it work briefly. Then you can rinse it with cold water.
Wash the clothes after treatment as usual in the washing machine.
Important: always test whether the fabric can tolerate the cleaning agent on an inconspicuous area.
Hairspray can remove paint stains from clothes. To do this, spray the hairspray onto the stain.
Leave it on for about five minutes to work in. After that, you can wash the area with warm water and a sponge. Repeat the process until the paint stain is no longer visible. You can then wash the clothes in the washing machine.
If you want to remove wall paint from clothes in the washing machine, you should pre-treat them. You can do this, for example, using a mild detergent. However, home remedies such as baking soda or lemon juice are also suitable.
Once you have pre-treated and rinsed the clothes, you can then wash them in the washing machine as usual.
5. Removing wall paint: Conclusion
Choosing the right method for removing wall paint depends on the substrate and the type of paint. Painting over old wall paint is a quick and often sufficient solution. The complete removal of the wall paint requires more time and effort and practical skill.
Whether scraping, sanding or removing with solvent – always protect yourself with a respirator, safety goggles and gloves. For demanding work, it makes sense to consult a professional.
